- | Peptide | Primary Mechanism | Tissue Target | Standard Research Dose | Administration Frequency | Key Advantage | Bottom Line ||—|—|—|—|—|—|| TB-500 (Thymosin Beta-4) | Upregulates actin, promotes angiogenesis and cell migration | Blood vessels, periosteum, connective tissue | 2–5mg per injection | Twice weekly for 4–6 weeks | Fastest vascularization of damaged tissue. Critical when blood flow to the periosteum is compromised | Best choice for chronic shin splints where inflammation has reduced local circulation || BPC-157 (Body Protection Compound-157) | Stabilizes nitric oxide pathways, reduces inflammatory cytokines, enhances collagen deposition | Tendons, ligaments, periosteum, gut lining | 250–500mcg per injection | Once or twice daily | Only peptide proven to accelerate tendon-to-bone healing in published research. Directly applicable to periosteal microtears | Gold standard for acute shin splint cases requiring rapid collagen repair || GHK-Cu (Copper Peptide) | Stimulates fibr
